Admin Dashboard Served as "script"

System Information
  • Strapi Version: 3.5.4
  • OS: Docker
  • Database: MySQL
  • Proxy: Ngninx

I started porting my how application (including strapi) to docker, is developed everything locally und it worked, so I started deploying to the live server. Somehow my admin-dashboard is served as “script” and i get the following error in the console “Uncaught SyntaxError: expected expression, got ‘<’” as the page stays blank. What could be the problem here. The only thing changes from my local instance to the live instance is that im using https / ssl encryption.

This is the part of my nginx configuration:

location /api/ {
proxy_pass http://strapi/;
proxy_http_version 1.1;                                                                                                 
proxy_set_header X-Forwarded-Host $host;                                                                                
proxy_set_header X-Forwarded-Server $host;                                                                              
proxy_set_header X-Real-IP $remote_addr;                                                                                
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;                                                            
proxy_set_header X-Forwarded-Proto $scheme;                                                                             
proxy_set_header Host $http_host;                                                                                       
proxy_set_header Upgrade $http_upgrade;                                                                                 
proxy_set_header Connection "Upgrade";                                                                                  
proxy_set_header X-Content-Type-Options "nosniff";                                                                      
proxy_pass_request_headers on;                                                                                      } 

Also as a proxy I’m using nginx. Hope anyone can help me or give me a hint in the right direction, thank you.
